Ted Cruz is not releasing his delegates in at least three states, a sign he may hold onto some clout at this summer's Republican National Convention. Cruz sent a letter to Republican state parties in at least Kansas, Oklahoma and Texas on Monday informing them that he plans to keep the delegates he won bound to him... Trump is the presumptive nominee and is on a path to clinch the 1,237 delegates needed to earn it on the first ballot, but holding on to his delegates could help Cruz exercise at least some control over convention rules and procedures.
